WATCH.

Specification of Letters Patent.

latented Mar. 12, 1918.

Original application filed September 3, 1913, Serial No. 788,024.Divided and this application filed February To all whom it may concernBe it known that I, LOUIS S. Armament, a subject of the King of Greece,residing at Athens, Greece, have invented certain new and usefulImprovements in Watches, of which the following is a full, clear, andexact description.

This invention relates to watches and more particularly to the mountingwhich supports the dial in place upon the movement.

The object of the invention is to protect the dial against injuriesresulting from the shocks or jars to which the dial is subjected whenthe watch is dropped or otherwise carelessly handled, for, as is wellknown, the face of the dial which carries the numerals indicatingthe'divisions of time is coated with a layer of enamel or some otherfragile substance which is easily cracked or chipped.

With this object in view, the invention consists of a resilient mountingfor the dial which supports it upon the movement. Preferably thisresilient mounting is so constructed that the dial is supported inspaced relation to the front face plate of the movement and is designedto permit the independent movementof the dial in all directions. In thespecific embodiment of the invention shown. this is accomplished by aspring fincer projecting from the rear face of the dial which issuitably secured to the front face plate of the watch movement.

R ferring to the drawings;

Figure 1 shows in elevation a watch having its dial mounted inaccordance with the pr ciples of my invention;

Fig. 2 is a central section through such a watch with the casinoremoved;

Fig. 3 is a detail showino a rear elevation of he improved form of dial;and

Fig. 4 is a front elevation of the watch movement showing the means forsecuring th dial to the same.

The improved form of mounting is adapted to be used in conjunction withany standard make of watch. but the type of watch shown is one whi h hasbeen designed to protect various other parts of the watch movement andcasing from injury and is shown and described in my application SerialNo. 788.024. filed September 3. 1913, of. which application the presentcase is a of the dial in all directions.

Serial No. 30,854.

division; the watch case comprising a casing 1 which is provided withshock absorbing devices 2 consisting of segmental shaped partsresiliently mounted in the casing. An open face watch is illustrated anddisposed at the rear of the watch crystal is a dial 3. This dial isshown in section in Fi 2 and consists of a thin metallic disk 4. Thedisk at is coated with a layer of enamel or other fragile material 5upon which are printed the numerals indicating the division of time. Asis obvious, the coating 5 is easily cracked or chipped when the watch isroughly handled and to prevent this, the dial is mounted in the mannerwhich will now be described.

Surrounding the peripheral edge of the dial is a rim 6 which carries aresilient finger 7 projecting radially toward the center of the disk.This finger extends over the rear face of the dial and is offsetlaterally therefrom as at 8. The watch movement is of the usualconstruction and consists of the plates 9 and 10 which are joinedtogether by posts or pillars 11, 12, etc, the gears and other portionsof the movement being incased between these plates. The free end of theoffset finger *7 is secured to the front face plate 9 of the movement sothat the dial is spaced from this plate a sufiicient distance to permitan independent movement One way in which this may be accomplished is byproriding' a post 12 having a slot therein into which the free end ofthe finger fits where it is securely held by a. set screw 14. The postmay be mounted on the platein any desired manner and in the form shownthe shank of the post passes through the plate and has an ollset end 15which engages an offset on the pillar 12. The dial is provided with acentral aperture or opening 16 through which the shafts 17, which carrythe hands 18 of the watch, project, which opening is made sufficientlylarge to insure that the surrounding edge or wall will not engage theshafts 17 when the dial is moved relatively to the watch movement. Theresilient finger 7 described is of sufficient resiliency to permit thedial to have a slight movement independent of the works in alldirections, and should the watch be dropped, the resilient finger 7 willtake up the force of the impact of the blow which would otherwise betransmitted to the dial itself and cause the dial to be cracked, chippedor otherwise injured.

Claims:

1. In a watch, a movement includin a front face plate, a dial, a rimsurrounding the dial, and resilient means connecting the rim to thefront face plate of the movement and holding the dial in spaced relationto the movement.

2. In a watch, a movement having a front face plate, a dial, a resilientfinger projecting from the rear face of the dial, and means carried bythe front face of said movement for securing the free end of said fingerto said front face plate, said fin 'er extending substantially radiallyinwardly toward the center of the dial and having a portion thereofoffset, whereby said dial is maintained in spaced relation to the frontplate of said movement.

3. In a watch, a movement, a dial, a post carried by the front faceplate of said movement, said post having a slot therein, and a resilientfinger carried by said dial having its free end secured in said slot.

4;. In a Watch, a movement, a dial, a rim surrounding the dial, aresilient finger carried by the rim, and means for securing the free endof the finger to the movement.

In witness whereof I subscribe my signature.
